16 Claims.

The invention relates to interlocking slide fasteners and particularly. to the operating sliders therefor, in which the pull device or pull tab se-'- cured to the slide for effecting the interlocking r, of the fastener element is .so constructed as to constitute a means for locking the slider after it has performed its function of interlocking the fastener elements in position.

A particular object of the invention is to provide a pull tab for the slider of an interlockin slide fastener structure which will function as a spring to effect a closure for the collar of a shirt,

the waistband of skirts, trousers, and like garments. A more particular object of the invention is to provide a pull tab for such slider formed of asingle piece of material so constructed as to have, when assembled with a slider, a spring action. The utility of the tab, when applied to a slide fastener structure upon a shirt, blouse, skirt to or pair of trousers, is substantially the same as that of a button, it being utilized in effecting the closure of the garment by being inserted into a button hole and thereafter pressed down so as to form a closure and prevent the collar or waist- :5 band of the garment from opening.

In the application of slider fastener structures of the prior art to garments such as a shirt or a skirt, the garment is provided with a button on the shirt collar or on the waistband. In the 0 former instance, a collar button passing through two buttonholes is sometimes used. In accordance with my invention, the necessity of using buttons as the closure means is entirely eliminated and the construction of such garments is, 5 therefore, simplified. One advantage of my inveiition thus lies in the, saving of money by the elimination of the necessity of providing buttons; other advantages reside in the facility with which the closure of the garment can be effected without recourse to collar buttons or the like and the elimination of attendant annoyance, for instance, in the loss of a collar button.

In its broadest aspect, a pull tab constructed in accordance with my invention is constituted 5 of a single piece of metal punched from spring bronze or brass which, in two embodiments of the invention illustrated and described, is then sheared and deformed in a particular manner for application to the slider, and in the other of the.

I three embodiments illustrated and described, is bent so as to constitute overlapped parts of a single pull tab for application to the slider. The pull tab in all of the embodiments is so constructed and formed as to have a spring action.

; Particular embodiments of my invention are illustrated in the accompanying drawings in which Fig. 1 shows the application of one form of my invention to a waistband of a skirt or of a pair of trousers to effect the closure thereof without the use of buttons; Fig. 2 is a plan view of one embodiment of my invention; Fig. 3 is a side view. partly in section, of the pull tab constructed in accordance with my invention and applied to the slider, showing the pull tab in position both normal and actingas the closure means; Fig. 4 is a plan view of the pull tab before deformation; Fig. 5 is a side view of the pull tab showing in dotted lines its form after deformation; Fig. 6 is a plan view of a second embodiment of my invention; Fig. 7 illustrates the op-- eration of said second embodiment with three positions of the pull tab being shown; Fig. 8 is a plan view of the punched-out blank of which the pull tab of such second embodiment is formed; Fig. 9 is a plan view of still another em-.

bodiment of my invention; Fig. 10 is a vertical section through the pull tab and slider of the last named embodiment of my invention showing the pull tab in normal and in locking position; and Fig. 11 shows my novel pull tab structure in position upon the collar of a shirt to effect the closure thereof.

Referring more particularly to the drawings, in which similar reference characters identify similar parts in the several views, and more particularly to Figs. 1-5 thereof, l2 designates the slider controlling the engagement and disengagement of the interlocking fastener elements. Such slider comprises top and bottom wings l3 and I4 respectively connected by the integral neck [5 and the cam l6 effecting spreading of the fastener elements. slider, by means of the protruding boss or lug I1, is attached the pull device or tab l8.

Such pull tab may be punched from spring bronze or brass provided with an elongated aperture l9 and a circular aperture 20, the tab being sheared along its center line between the apertures l9 and as well as between the rivet elements 2| and 22 near its upper extremity.

The pull tab is then deformed to the form shown in Fig. 5, the upper and lower extremities thereof being bent in opposite directions to substantially the extent indicated. The pull tab is applied to the slider l2 by means of the two rivet elements 2! and 22 which straddle the depending portion of lug IT. The material of the tab immediately below the rivets 2| and 22 is rounded at 25 and 26 to fit the recesses 23 and 24, the difference between the rounded surfaces 25 and To the top wing l'3 of the 26 and the width of the elongated aperture l9 constituting the clearance.

The operation of the slider and pull tab as applied to the waistband of a skirt or of a pair of trousers provided with a slide fastener structure, is illustrated in Fig. 1. In such application, the pull tab is brought to the upper extremity of the slide fasteners, the pull tab being in its normal position shown in dotted. lines in Fig. 3. When the slider has reached its uppermost position, effecting an interlocking of the slide fastener elements, it is passed through the buttonhole 21 and depressed to the position thereof shown in full lines in F g. 3.

,It will thus be seen that the pull tab in its normal position extends outwardly from the slider l2 in effecting the interlocking engagement of the fastener elements and is brought thereafter to the closure .position by its spring action, in which the rounded surfaces 25 and 25 are compressed during the bending operation so as to have them enter the recesses 23 and 24, being sprung into such recesses as soon as such rounded surfaces are opposite the upper extremities of' such recesses. After being positioned so as thus 'to effect a closure of the waistband of the garment, the pull tab may be raised from its full line position shown in Fig. 3 to its dotted line position only by a positive action to cause the rounded surfaces 25 and 26 to snap out of engagement within the recesses 23 and 24.. The

bent or folded along the horizontal median line thereof 28 to constitute a pull tab having two overlying portions 29 and 30. The slider, with a single feature of difference, is substantially like the slider of thefirst embodiment, the pull tab'being secured to the protruding boss or lug of the slider by means of the oblong apertures 3| of thepull tab. The slight difference in the slider of this embodiment of my invention and that of the first embodiment is that such protruding bos or lug is provided with a square slot 32 to accommodate the tab. The pull tab is shown in full lines in Fig. 7 in the closure position in which the upper extremities of the two parts thereof 29 and 30 are separated by their inherent spring action, with the extremities of the two parts pressing against the inner side faces ofthe slot. The pull tab may be brought into normal, operative position in which it is at right angles to, the slider, and also to the opposite vertical closure position, so as to extend upwardly as shown in dotted lines in Fig. 7. The slider will remain in any one of these three positions by reason of the'action of the twoportions. thereof in which they function as a spring being forced apart so as to have their extremities press against the flat inner surfaces of the slot. The pull tab. will remain in the particular position of the three illustrated because in any turning motion, the tab would have to overcome the spring'resistance due to the fact that the portions thereof 29 and 30 must be brought together while the Pull tfib is removed from any of the three positions. Thus, as soon as suchpull tab is removed from the position thereof ,shown in full lines in Fig. 7, I the two portions thereof 29 and 30 will be brought together so as tocontact each other and will be retained in such contacting position until brought to a position nearer to that in which the pulltab is at right angles to the slider than to the vertical position thereof. As soon as the tab has' been brought to a position in which it is at an and described for effecting the closure of a shirt collar or the waistband of a garment, substantially as described with respect to the first em bodiment of my invention.

Still another embodiment of my invention is illustrated in Figs. 9-11. In such embodiment, the pull tab is likewise punched from spring bronze or brass, the material being sheared in two placeslongitudinally of the tab so as to form a tongue 33. The pull tab is then given the form as shown in Fig. 10 by bending the upper and lower extremities thereof in opposite directions.

The spring pull tab illustrated in Figs. 9-11 functions substantially like that shown in Figs. 6-8 inclusive, the only difference being that in the embodiment of Figs. 6-8, the tab, by its duplex structure, acts on each side of the aperture in the lug of the slider, while in the embodiment illustrated in Figs. 9-11, the spring, constituted of the tongue 33, formed in the tab 35, acts upon the top surface of the lug 34 of the slider.

Thus, when the pull tab f Figs. 941 is in its closure position, the tongue 33 rests against the outer face of the slider lug and as it is being brought to the upper, normal, or slider operative, position, illustrated in dotted-lines in Fig.

v 10, the upper extremity of the tongue 33 slides along the curved surface of the lug to the top surface thereof, in which position it will retain the pull tab in such dotted line position, so that the pull tab may be passed through the buttonhole of the collar or garment and then brought back to its closure position.

It Will be noted that the slider of the last described embodiment of vmy invention differs from the slider of the first two embodiments described in that the protruding boss or lug 34 thereof is formed. with an outer surface constituting a cam upon which the upper extremity sembly of the various elements'therecf, may be made without departing from the invention.
